Kry'Shaltan, Pestilence

You control each creature with an Infection
counter on it
Whenever a creature you dont control becomes
tapped, roll a d20. If the result is 10 or higher,
put an Infection counter on that creature.
Sacrifice a creature with an Infection counter: It
deals damage equal to its toughness to target
creature
I'm going to make them wish they had a god.
